Be it known that ll, )BERNARD l-l. SKELLY, a citizen of the United States, residing at the cit of Bridgeport, in the count of Fairfie d and State of Connecticut, ave invented certain new and useful lmprovements in Nozzle Attachments for Oil Guns; and l do declare the following to be a full, clear, and exact descri tion of the invention, such as will enab e others skilled in the art to which it appertains to make and use the same.

This invention relates to a nozzle attachment for an oil gun, whereby the gun may be utilized in connection with a nipple that is not so constructed as to receive the nozzle interiorly in telesco ing relation.

Heretofore, nipp es secured to the part to be lubricated have been formed with a hollow cup for receiving the nozzle of the oil gun, and with an exteriorly beveled element u standing from the bottom of the cup and aving an oil inlet which is normall closed at its lower end by a spring chec valve, and the seating ofthe nozzle within the cup automatically opened a spring check valve in the nozzle so as to admit the oil, as is shown and described in my pending application, Serial Number 412,488, tiled September 24, 1920.

But this construction necessitated the provision of a special form of nipple so that the nozzle of the oil gun, acting as afmale member, would enter the nipple or female member, and it is the object of the present invention to enable the nozzle of the'oil gun to be used in connection with ordinary nipples, and at the saine time to require that no change in the construction of the nozzle need be made.

ln the drawings:

Figure 1, is a side elevation partly in section of an oil gun equipped with the present invention;

Figure 2 is a section on line 2-2 of Figure 1;

Figure 3, is a view similar to Figure 1, of a modied form of the invention, and

Figure 4, is a detail view in section of a further modied form.

ln proceeding in accordance with the present invention, a sleeve 1 is provided and formed to slide at one end over the nozzle N of an oil gun G and being detachable therefrom, and at its opposite end being formed to snugly slide over the nipple A.. At or 'adjacent to the center of the 1nterior of the sleeve is a disk 2 which is here shown as driven into the sleeve andl abutting a shoulder 3, though any other suitable or preferred means for' holding the disk may be resorted to if desired. 'lhe disk has a central oil passa e and perforated bosses or projections 4 an 5 extendin respectively upwardly and downwardly m the opposite faces of the disk, the perforations registering with the disk opening so that a continuous oil passage 6 results. The projection 4 en ages and opens the valve 12 of the gun and preferably has a conical periphery so as to conformably engage in the outlet of the gun. The projection 5 is formed at its outer end with a square beveled countersunk portion 7 which at its outer extremity engages the ball valve 8 of the nipple A and unseats the latter so that the oil then freely passes thro h the passage 6 and countersunk portion and enters the nipple, the rojection 5 entering the nipple as shown in i e 1.

ln the modified form s own in Figure 3 the projection 5 is omitted, the lower or bottom face of the disk 2 being consequently flat, a ber or other washer 9 being employed which has its opening in register with the oil passage 6 so that when the sleeve l is forced over the nipple A, the washer 9 will seat on the outer end of the ni ple to form an oil seal. ln this form of t e invention, the pressure of the oil upon extruding operation of the gun is relied upon to unseat the valve 8, whereas in Fi e 1, the valve is positively held unsea `throughout the time of attachment of the oil gun to the nipple.

A further modification is illustrated in Figure 4, wherein the upper projection 4' is of uniform diameter and formed to unseat the gun valve as in the instance or the projection 4 of Fi l, being used in connection with guns t e mouths of the nozzles' of which are straight.

lin all forms of the invention it will be seen that the invention provides an attachment which can be easileand quickly a plied and removed from t and wliic can be quickl slid over nipp es of the type shown and e oil conducted directly into the nipple by the projection 5 of Figures 1 and 4 .so as to not enter the sleeve, while in Figure 3, the washer 9 acts to prevent the latter. by sealing the nipple mouth.

What is claimed 1s:

1. An attachment for oil guns embodylng a sleeve formed at one end to be received over the nozzle of a grease gun and at its opposite end to be telescoped over a nipple, a shoulder interiorly of the sleeve, and a disk in the sleeve abutting the shoulder and having upper and lower projections the former to engage and unseat the gunrvalve and the latter to engage and unseat the n1p ple ball valve, the disk and projections having an oil passage therethrough, the lower disk being formed with a non-circular countersink to engage the ball valve.

2. An attachment for oil guns embodying a sleeve formed at one end to be received over the nozzle of a grease gun and at its opposite end to be telescoped over a nipple, and a disk in the sleeve between the ends thereof and having an upper and a lower projection with an` oil passage. formed through the disk and both projections, the upper projection being formed to unseat the Lezcano gun valve and the lower projection to unseat the ball valve of the nipple.

3. An attachment for oil ns embodying a sleeve formed at one endg-io be received over the nozzle of a grease gun and at itsy opposite end to be telescoped over a nipple, and /a disk in the sleeve between the ends thereof and having an upper projection :formed to enter the gun nozzle and to unseat the valve thereof, the disk and projection having an oil passage.'

4. An attachment for oil guns embodying a sleeve formed at one end to be received over the nozzle of a grease gun and at its opposite end to be telescoped over a nipple, means in the sleeve to unseat the gun valve and means to direct oil from the unseating means into the nipple.

5. An attachment for oil guns embodying a sleeve formed at one end to be received over the nozzle of a grease gun and at its opposite end to be telescoped over a nipple, and means in the sleeve to unseat the gun valve and to allow the oil to enter the nipple.

In testimony whereof I afiix my signaturev hereto.

BERNARD EL SKELLY.
